A certain bacteria is placed in a jar. Initially, there are 25 bacteria. Every hour, the number of bacteria quadruples. How much bacteria will there be in 6 hours?
Hello!
So, to answer this question we need to note that quadruple = x4
25 (our initial count) x 4 = 100
100 (after one hour) x 4 = 400
400 (after two hours) x 4 = 1600
1600 (after three hours) x 4 = 6400
6400 (after four hours) x 4 = 25600
25600 (after five hours) x 4 = 102400
So to answer your question, after six hours, there will be 102,400 of that bacteria in the jar.

A local garden club had 14 members with a mean age of 34. Then two new members joined. One was 24 years old, and the other was 36 years old. How did the mean age change after they joined?
Without knowing the ages of all the different members of the club, I believe that the mean would go down due to 24 being an outlier. You generally take the mean by adding up all the numbers and dividing by all the # of given values. Outliers such as 24 would skew the results leaning none way or the other, in this case making it lower than the previous mean.

f(x) = (x - 4 )(x - 6) = 0
because you can see when each factor is equal to zero
x - 4 = 0 ⇒ x = 4
x - 6 = 0 ⇒ x = 6
evaluate 4 to the power of 3 . (100/25) - 5 to the power of 0
Hey there!!
Remember :-

1.calculate a unit rate for each size
2. which size is the best buy
Answer:
Part 1) The units rates are
A) [tex]0.1165\frac{\$}{oz}[/tex]
B) [tex]0.1656\frac{\$}{oz}[/tex]
C) [tex]0.0516\frac{\$}{oz}[/tex]
D) [tex]0.0579\frac{\$}{oz}[/tex]
Part 2) The best buy is the size 48 1/4 oz
Step-by-step explanation:
we know that
To find out the unit rate divide the total cost by the total volume
Part 1) Calculate the unit rate for each size
case A) we have
8 1/2 ounce bottle costs $0.99
Convert mixed number to an improper fraction
[tex]8\frac{1}{2} =\frac{8*2+1}{2}=\frac{17}{2}\ oz[/tex]
Find the unit rate
[tex]\frac{0.99}{(17/2)}= 0.1165\frac{\$}{oz}[/tex]
case B) we have
18 2/2 oz. bottle costs $1.49
Convert mixed number
[tex]18\frac{2}{2} =18+1=19\ oz[/tex]
Find the unit rate
[tex]\frac{1.49}{19}= 0.1656\frac{\$}{oz}[/tex]
case C) we have
48 1/4 oz. carton costs $2.49
Convert mixed number to an improper fraction
[tex]48\frac{1}{4} =\frac{48*4+1}{4}=\frac{193}{4}\ oz[/tex]
Find the unit rate
[tex]\frac{2.49}{(193/4)}= 0.0516\frac{\$}{oz}[/tex]
case D) we have
64 3/4 oz. carton costs $3.75
Convert mixed number to an improper fraction
[tex]64\frac{3}{4} =\frac{64*4+3}{4}=\frac{259}{4}\ oz[/tex]
Find the unit rate
[tex]\frac{3.75}{(259/4)}= 0.0579\frac{\$}{oz}[/tex]
Part 2) which size is the best buy
we know that
The best buy is the one with the smallest unit rate
so
[tex]0.0516\frac{\$}{oz}[/tex]
The best buy is the size 48 1/4 oz

If the complex number x = 3 + bi and |x|^2 = 13, which is a possible value of b?
A. 2
B. 3
C. 9
D. 10
20 points to the brainliest user!!!!
If x=3+bi, then
[tex]|x|=\sqrt{3^2+b^2}.[/tex]
You know that [tex]|x|^2=13,[/tex] then
[tex]\left(\sqrt{3^2+b^2}\right)^2=13,\\ \\ 9+b^2=13,\\ \\b^2=4,\\ \\b=\pm 2.[/tex]
Two possible complex numbers satisfy these conditions:
[tex]x_1=3+2i, \ x_2=3-2i.[/tex]
As you can see the possible value of b is 2.
Answer: correct choice is A.
The possible value of b in the given complex number is 2 (Option A). This is found by using the definition of modulus of a complex number and solving the resulting equation.
Explanation:This question requires understanding of complex numbers and their modulus. A complex number is a number of the form a + bi, where a and b are real numbers and i is the imaginary unit with the property i^2 = -1.
|x|^2 represents the square of the modulus (or absolute value) of the complex number x which is defined as |x|^2 = a^2 + b^2. Given in the question, x = 3 + bi and |x|^2 = 13. Thus, by substitution, we get 13 = 3^2 + b^2.
Performing arithmetic operations, it's equivalent to b^2 = 13 - 3^2 = 4. To solve for b, we take the square root of both sides. Because b can be positive or negative, we get b = ±2. Therefore, from the options given, the possible value of b is 2 (Option A).

Complete the ratio table to show ratios equivalent to 16:10. The blank parts are what's missing. Thank you
2 8
36 9 72
The ratio table is completed by finding values that are equivalent to the ratio 16:10, which simplifies to 8:5. The corresponding values are calculated by setting up proportions based on the original ratio.
Explanation:To complete the ratio table that shows ratios equivalent to 16:10, we first understand that the ratio can be simplified to 8:5 by dividing both terms by 2.
We can use this simplified ratio to find missing values in the table.
For the row with 2 in the first column, the second column should be 2 times 5/8 (since 8:5 is equivalent to 16:10) to maintain the ratio equivalency.
This gives us the value 2*(5/8)=1.25.
In the row where the second column is 36, we need to determine the equivalent in the first column.
We set up the proportion 8/5=x/36, and solving for x gives us 8*(36/5)=57.6.
The last row given is 72 in the second column.
To find the corresponding first column value, we use the ratio 8/5=x/72 and solve for x to find 8*(72/5)=115.2.
The filled in ratio table should look like this:
2 : 1.2557.6 : 36115.2 : 72x + 6 = x

Solve |2x - 5| = 4. {x | x = -4.5 or x = 4.5} {x | x = 0.5 or x = 4.5} {x | 0.5 < x < 4.5}
Answer:
{x | x = 0.5 or x = 4.5}
Explanation:
Before we begin, remember that:
The modulus gives the positive value of what's inside it.
This means that:
|a| = |-a| = a
Now, for the given, we have:
|2x-5| = 4
From the above rule, we can deduce that:
either:
2x - 5 = 4
2x = 4 + 5 = 9
x = 4.5 ............> first solution
Or:
2x - 5 = -4
2x = 5-4 = 1
x = 0.5 ..........> second solution
Now, we check:
at x = 4.5: |2(4.5)-5| = |9-5| = |4| = 4 ..........> first solution verified
at x = 0.5: |2(0.5)-5| = |1-5| = |-4| = 4 .........> second solution verified
Hope this helps :)
Answer:
{x | x = 0.5 or x = 4.5}
Step-by-step explanation:
Solve the equation. If there is no solution, write no solution. 5|x + 3/4| = 10

Write an expression that shows how to use the halving and doubling strategy to find 28x50
Write an expression that shows how to use the halving and doubling strategy to find 28x50
Halving strategy means we divide by 2
Doubling strategy means we multiply by 2
We apply halving strategy for 28 and doubling strategy for 50
Half of 28 is 14
Double of 50 is 100
So 14 * 100 = 1400
Now we check with 28 * 50
28 x 50 = 1400
So required expression is

A local hamburger shop sold a combined total of 593 hamburgers and cheeseburgers on Thursday. There were 57 fewer cheeseburgers sold than hamburgers. How many hamburgers were sold on thursday
Answer:
325 hamburgers were sold on Thursday.
Step-by-step explanation:
Let h be the number of hamburgers and c be the number of cheeseburgers.
Using this information we can set up two equation as:
[tex]h+c=593\\c=h-57[/tex]
Now we need to solve these two equations to get the value of number of hamburgers. For that we use substitution method as shown below:
[tex]h+h-57=593\\2h-57=593\\2h=650\\h=325[/tex]
Therefore, the number of hamburgers sold on Thursday were 325.

If the measure of angle ABF=6x+26 and the measure of angle EBF=2x9 and measure of angle ABE= 11x-31 find the measure of angle ABF
Its not clearly given that whether EBF = 2x + 9 or 2x - 9.
I have written the solution for both.
If EBF = 2x + 9,
then ABF = 6x + 26 and ABE = 11x - 31.
Now, ABE = ABF + EBF
11x - 31 = (6x + 26) + (2x + 9)
= (6x + 2x) + (26 + 9)
= 8x + 35
11x - 8x = 35 + 31
3x = 66
x = 22
Therefore, ABF = 6x + 26 = 6(22) + 26 = 132 + 26 = 158°
If EBF = 2x - 9,
then ABF = 6x + 26 and ABE = 11x - 31.
Now, ABE = ABF + EBF
11x - 31 = (6x + 26) + (2x - 9)
= (6x + 2x) + (26 - 9)
= 8x + 17
11x - 8x = 17 + 31
3x = 48
x = 16
Therefore, ABF = 6x + 26 = 6(16) + 26 = 96 + 26 = 122°
The expression for angle ABF: ABF = 6x + 26 = 6(16) + 26 = 96 + 26 = 122°
What is the angleFrom the question: If EBF = 2x + 9, then ABF = 6x + 26 and ABE = 11x - 31.
When, ABE = ABF + EBF
11x - 31 = (6x + 26) + (2x + 9)
= (6x + 2x) + (26 + 9)
= 8x + 35
11x - 8x = 35 + 31
3x = 66
x = 22
Hence, ABF = 6x + 26 = 6(22) + 26 = 132 + 26 = 158°
When EBF = 2x - 9,
So, ABF = 6x + 26 and ABE = 11x - 31.
When, ABE = ABF + EBF
11x - 31 = (6x + 26) + (2x - 9)
= (6x + 2x) + (26 - 9)
= 8x + 17
11x - 8x = 17 + 31
3x = 48
x = 16
So, ABF = 6x + 26 = 6(16) + 26 = 96 + 26 = 122°

2x + y = 8---------(2)
subtract (2) from (1)
2x = -7
divide bothside by 2
2x/2 = -7/2
x= -7/2
we can substitute x = -7/2 in any of the equations.
Lets take equation (1)

c=7
Now put it in the equation.
3.2(7)+1.7=24.1
3.2c + 1.7 = 24.1'
c = (24.1 - 1.7) : 3.2
c = 22.4 : 3.2
c = 7
